UPDATE: -- Police say the teen has been found safe and in good health.
Calgary Police are looking for a 13-year-old girl who has been missing since Friday.
Andree Lou Amamio left her school in the Beltline area after class on Friday and joined friends.
She then boarded a No. 6 Calgary Transit bus by herself at approximately 6 p.m. at 1 Street and 8 Avenue southwest.
"Her family has not heard from the teen since yesterday when she left for school, which is very uncharacteristic for her," police said in a statement.
She was wearing a dark jacket, jeans, a dark-coloured Nike toque and a black backpack.
